I recently found these in the produce section of my local Food Emporium, near the tomatoes. I guess they’re a different kind of tomato – plump and juicy and very mild, not acidic at all.
They’re very deep red, almost brownish in color, both inside and out. Citrus with high acidity tends to give me a stomachache, which these didn’t do at all. I loved them. Not too expensive either. Very happy find!
